The SEM is especially useful when combined with Energy Dispersive X-ray spectroscopy (EDX), which can be performed in the microscope, enabling very small areas of the sample to be analyzed for their elemental composition. One disadvantage of the SEM approach is related to its high resolution. Only a very small area can be analyzed and the fracture pattern can rapidly become very complex to inte...

in the present work, bi2s3 nanostructures have been synthesized with the aid of thioglycollic acid (tga) a solvent, capping agent, and sulfide source in the presence of ultrasonic method. the as-synthesized products were characterized by x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (eds), scanning electron microscope (sem), and photoluminescence (pl) spectroscopy. the band gap ...

Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...

Purpose: With the introduction of combinatorial chemistry and high throughput screening, the properties of new chemical entities shifted towards higher molecular weight and increasing lipophilicity that results in decreasing aqueous solubility. It is not surprising that many drug candidates have poor water solubility since the initial selection of drug candidates are based on activity alone. Ot...

Nano-zeolite CoAPO-5 as a member of AFI family, was synthesized via a hydrothermal treatment, and structurally characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray analysis (EDAX). The effects of crystallization temperature and time on the structure of these powder products were studied. XRD patterns of the synthesized powders revealed a h...

OBJECTIVE To examine the ultrastructure of six light-cure orthodontic adhesives with scanning electron microscope (SEM) and transmission electron microscope (TEM), microhardness tester, and energy dispersive X-ray microanalyzer (EDX). MATERIALS AND METHODS The orthodontic adhesives evaluated were Transbond XT, Light Bond, BeautyOrtho Bond, Kurasper F, Heliosit Orthodontic, and Salivatect. Spe...

ZnO nanorods array films were coated on a glass template through a two-step chemical process. First, a sol-gel spin coating method was used to produce a ZnO seed layer and after that, the ZnO nanorods arrays were grown on it through a low temperature aqueous method. Synthesized films were studied by scanning electron microscope (SEM) and X-ray diffractometer (XRD). X-ray diffraction results sho...

Abstract This paper mainly studies the influence of high temperature conditions on Li-MnO 2 primary battery, and analyzes performance battery by testing capacity, voltage internal resistance product. Through impedance test, different polarization differences between products stored at normal were analyzed. The effects environment macro structure micro material components analyzed means electron...
